Interesting blog post by Brian Thompson. Excerpt below.
Within each thing, are many things.
It’s a sublime and enlightened teaching of non-duality that is clearly expressed through the following verse:
“This is, because that is.
This is not, because that is not.
This ceases to be, because that ceases to be.”
When we apply this teaching into our lives, we gain deeper insight into the true nature of things. We begin to understand that nothing is an island unto itself. No thing is separate all on its own, and that no thing is completely self-contained or self-reliant. Everything that is, exists solely because of other events that have also co-arisen. All things are dependent upon cause and effect. This is true not only for our physical actions, but so too with all of our mental formations and the emotional happenings within our mind.
It's never just one thing. Nothing arises from itself alone.
Neither exists without the other. Together, they are one whole.
Believe nothing you cannot verify for yourself, Son.
